When your season starts with an early October storm cycle and doesn't let up until June corn, you need gear that will go the distance. The Primo is the most durable, lightweight shell pant we make for daily riding all season long. A tough 3-layer recycled nylon shell is bonded with waterproof/breathable GORE-TEX Performance Shell on the outside for protection and durability. A DWR (durable water repellent) finish prevents saturation and repels even the wettest snow conditions. Other features include a gusseted crotch for mobility, coated, watertight Slim Zips for reduced bulk, articulated knees, external thigh vents, tough scuff guards and internal gaiters.
